[Prevention of HIV transmission: application of the theory of reasoned action to the prediction of condom use]. / Prevencion de contagio de VIH: aplicacion de la teoria de accion razonada a la prediccion de uso del condon.

PIP: 1203 sexually active workers in six government agencies in Mexico City participated in a study of the applicability of the theory of reasoned action to prediction of condom use for AIDS prevention. The theory of reasoned action is one of a series of models of attitudes that have had consistent success in predicting various types of intentions and behaviors, especially in the area of sexual and contraceptive behavior. The theory specifies that the intention of executing a particular behavior is determined as the function of attitude toward the behavior and a social factor termed "subjective norm", referring to the perception of social pressure supporting or opposing a particular behavior. The 1203 subjects, who ranged from low to high educational and socioeconomic status, completed self-administered questionnaires concerning their beliefs, attitudes, and intentions regarding condom use, motivation to comply with the subjective norm, and actual condom use. Various scales were constructed to measure the different components of the theory. Hierarchical regression analysis was carried out separately for men and women and for condom use with regular or occasional partners. The model explained over 20% of condom use behavior. The total explained variance was similar in all groups, but the components of the model determining the variance were different. Personal beliefs and attitudes were more important in reference to occasional sexual partners, but the subjective norm and motivation to comply with the reference group were more important with regular sexual partners. The results demonstrate the need for interventions to be adapted to gender groups and in reference to regular or occasional partners.^ieng

Effect of sex education on the sexual and contraceptive practices of female teenagers in Mexico City.

PIP: After reviewing the literature on the relationship between sex education and sexual and contraceptive behavior, the National Research Council (1987) recently concluded that the existing evaluation of the effects of sex education on sexual and contraceptive practice is helpful but not sufficient. 1 possible explanation for the different results obtained are the diverse sociodemographic characteristics of the sample(s) of teens under consideration. Another aspect which might account for the differences seen in the literature focuses on the areas covered in the course. In Mexico, no studies have been undertaken which deal with the relationship between sex education and sexual and contraceptive behaviors. A study carried out with 392 adolescent females ages 16-17 of lower and middle lower socioeconomic status showed that merely attending a sex education course did not affect the initiation or continuation of sexual activity, contraceptive behavior, or even the perception of accessibility to contraception. Providing information on sexuality, partner relationships, and where contraception can be obtained does not appear to have any effect on sexual activity. Receiving information on pregnancy prevention and obtaining contraceptives was found to be related to contraceptive use. Although less dramatic, information about partner relationships and sexuality produced increases in contraceptive use.^ieng
